THEODORE DE LEMOS AND AUGUST W. CORDES, OF NEW YORK, N. Y.

CONSTRUCTION OF BUILDINGS.

SPECIFICATION forming part of Letters Patent No. 334,694, dated January 19, 1886.

Application filed June 5, 1885. Serial No. 167,730. (No model.)

To all whom, it may concern:

Be it known that we, THEoDoRE DE LEMos and AUGUST W. CoRDEs, of the city, county, and State of New York, have invented certain new and useful Improvements in Construction of Buildings, of which the following is a specification.

This invention relates to an improved construction of buildings to be used for offices, art-rooms, factory purposes Sac.; and the invention consists of a building the court-wall of which is constructed with step-shaped olfsets for the different stories, and with skylights for covering said offsets. The offsets are supported on iron beams above the floors, and the skylights closed by hinged metal shutters that are locked either close to the skylights or at an angle thereto.

In the accompanying drawings, Figure 1 representsa vertical transverse section through the court-wall of a building constructed according to our invention; and Fig. 2 is a detail vertical transverse section of the offsetwall and skylight of oneV story, drawn on a larger scale. v

Similar letters of reference indicate corresponding parts.

' Referring tol thedrawings, A A representthe doors of a building designed for office purposes, factories, art-rooms, and similar purposes. The wall of the light-court or courtyard of the building is constructed with stepshaped offsets B B, that extend from story to story farther back into the light-court or courtyard, as shown in Fig. l. The vertical walls of the offsets B B are supported on iron beams A', above the floors A A, and covered by inclined skylights C, that connect the upper end ofthe wall of one offset with the base of the wall ofthe next offset. To render the skylights fire-proof, iron shutters D are hinged near the upper end of the saine, which shutters are retained in closed or open position by suitable locking devices, d d', as shown, respectively, in dotted and full lines in Figs. 1 and 2. The shutters are moved into open or closed position by means of cords or chains dtd?, that pass over pulleys d3, as shown in Fig. 1. The windows in the offset-walls of each story are preferably closed by means of iron rolling shutters, whereby the entire rear wall is made to some extent fire-proof. By thus constructing the court-wall with backwardly-extending offsets and providing said offsets with sky-lights a considerably larger space is obtained at the rear end of the different stories, as all the spaceback of the vertical dotted line shown in Fig. 1 is gained thereby. The rear portions of the different stories are lighted in a much better and more direct manner by the skylights, which are thereby not dependent on the reflected light ofthe rear wall of t-he adjoining building.

This construction is specially adapted for buildings in large cities in which the ground is very valuable, as thereby the available yard area can be more advantageously utilized. NVe are aware that buildings having extensions covered by skylights have been used heretofore, and we do not lay any claim to this feature.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. A building the court-wall of which 1s made with step-shaped offsets for different stories, the offsets being covered by skylights, substantially as set forth.

2. A building the court-wall of which is made with step-shaped offsets for different stories, the walls of the offsets being supported on beams above the doors, and covered by inclined skylights, substantially as set forth.

3. A building the court-wall of which is made with step-shaped offsets for the differ-4 ent stories, skylights covering the offsets. hinged shutters, and devices, substantially as described, for locking the shutters in open or closed position, substantially as set forth.

' In testimony that we claim the foregoing as our invention we have signed our names in presence of two subscribing witnesses.
